[QUOTE="96dreamer, post: 16196987, member: 52560"] I noticed I had some of the pictures out of order. I was going to go back and fix it but it would have been to much of a pain in the ass. I wet-sanded before I took the motor out and painted it black so use your imagination. Back to the motor situation. January following the motor tear down I started the process of getting things ready for the rebuild. I previously mentioned that I had an engineering job at Sunnen and the equipment and knowledge I had access to was invaluable. I started by measuring the h beams to make sure they were in good shape. They are eagle H beams that should live at 800-1000 hp without issue. [ATTACH=full]1573044[/ATTACH] Everything looked great so I planned on reusing the rods. Brought the heads into work to start working on them. They were already torn down and cleaned from about a year earlier so the first thing I did was install new bronze valve guides and hone them to match each valve. I didn't get any pictures of this. I did learn the hard way to setup everything the correct way after honing the first guide about .040 to big. Had to press that one out and get some spares to finish the job. Threw the head in the vs-20 and opened up the id's of the intake and exhaust bowls. [ATTACH=full]1573045[/ATTACH] [ATTACH=full]1573046[/ATTACH] [ATTACH=full]1573047[/ATTACH] [ATTACH=full]1573048[/ATTACH] One of the honing lab techs that held my hand along the way convinced me to clean up the ports while I had it all apart. I made up some stands so I could rotate the heads on my work bench and lock them in place. [ATTACH=full]1573049[/ATTACH] [ATTACH=full]1573050[/ATTACH] He let me borrow his full porting setup which worked awesome. It consisted of a makita long neck grinder, variable voltage adjuster, and a large assortment of burrs, sanding drums and flap wheels. [ATTACH=full]1573051[/ATTACH] [ATTACH=full]1573052[/ATTACH] First ports and bowls cleaned up. I wasn't after hogging the ports out or doing anything drastic. Main focus was knife edging the intake divider, blending the short side radius on the intake and removing the casting marks. [ATTACH=full]1573053[/ATTACH] I marked all the gaskets not with the intention of matching them but just to make sure I didn't remove to much material anywhere. [/QUOTE]
